Abstract
Description
Technical Field
[0001] This application relates to the field of storage tank safety technology, and in particular to a cold leakage detection system. Background Technology
[0002] Large liquefied natural gas (LNG) storage tanks are critical facilities for energy storage and peak shaving, making their safety paramount. Cold leakage in large LNG storage tanks is a common type of facility failure in LNG receiving terminals, primarily caused by the settlement of the insulation layer. If a cold leakage occurs in an LNG storage tank, the LNG inside will undergo a phase change due to heating, producing a large amount of boil-off gas (BOG). This leads to increased consumption of cold stream in the recondenser, and may even cause stratification and turbulence of the liquid inside the tank, ultimately resulting in overpressure and rupture of the inner tank.
[0003] However, leak detection of LNG storage tanks is usually carried out by relevant personnel on patrol. Because the LNG storage tank is too tall, it is impossible to completely inspect the entire LNG storage tank. Therefore, there are problems such as low leak detection efficiency and inability to completely detect leaks in the storage tank. Utility Model Content

[0032] As described in the technical background, LNG storage tanks are critical facilities for energy storage and peak shaving, making their safety paramount. Cold leakage in large LNG storage tanks is a common type of facility failure in LNG receiving terminals, primarily caused by the settlement of the insulation layer. If a cold leakage occurs in an LNG storage tank, the LNG inside will undergo a phase change due to heating, producing a large amount of BOG gas. This leads to increased consumption of cold stream in the recondenser, and may even cause stratification and turbulence of the liquid inside the tank, ultimately resulting in overpressure and rupture of the inner tank.
[0033] Current technology typically involves LNG storage tank leak detection through routine inspections by relevant personnel. However, due to the height of LNG storage tanks, it is impossible to completely inspect the entire tank. Therefore, leak detection is inefficient and cannot fully detect leaks.
[0034] To address the aforementioned problems, this application provides a cold leakage detection system, including a drone equipped with a tank cold leakage detection device. The drone includes a frame. A control system is located at the center of the frame, and power systems are located at the four corners of the top of the frame, connected and controlled by the control system. Landing gears are located at the four corners of the bottom of the frame, and the tank cold leakage detection device is positioned between the landing gears. The tank cold leakage detection device is connected and controlled by the control system and is used to detect cold leakage in LNG storage tanks.
[0035] In this embodiment, a drone equipped with a tank leak detection device sends a command to its control system to begin leak detection when a leak detection of an LNG storage tank is required. The drone then begins the leak detection process. Therefore, this method improves the efficiency of leak detection and allows for a complete inspection of the LNG storage tank.
[0036] Then, in this embodiment, the power system and control system work together to ensure flight stability and more accurately detect tank leaks. The landing gear supports the drone and effectively cushions the impact of landing, thereby protecting the tank leak detection device carried on the drone.
[0037] Figure 1 A 3D diagram of a drone equipped with a tank leakage detection device, provided as an embodiment of this application. Figure 1 As shown, the UAV equipped with the tank leakage detection device includes: frame 1, power system 2, landing gear 3, and tank leakage detection device.
[0038] Specifically, the drone equipped with the tank leakage detection device also includes a control system, which controls the power system 2 and the tank leakage detection device.
[0039] In some embodiments, such as Figure 1 As shown, the tank leakage detection device includes an infrared lens 6 and a laser rangefinder 7.
[0040] Optionally, the tank leakage detection device also includes a wide-angle lens.
[0041] Understandably, the tank leakage detection device uses multiple optical components working together to combine three types of images to perform multi-dimensional detection of tank leakage, solving problems such as image distortion, inability to locate leakage defects, and low detection efficiency of traditional handheld infrared cameras.
[0042] In some embodiments, such as Figure 1 As shown, a control system is located at the center of the frame 1, and power systems 2 are located at the four corners of the top of the frame 1. The power systems 2 are connected to the control system. Landing gears 3 are located at the four corners below the frame 1. A tank leakage detection device is installed between the landing gears 3. The tank leakage detection device is connected to the control system and is used to detect leakage in liquefied natural gas (LNG) storage tanks.
[0043] Specifically, frame 1 constitutes the overall architecture of the UAV, supporting and connecting various components. Power system 2 provides power to the UAV. Landing gear 3 supports the UAV for takeoff and landing. The tank leak detection device collects various image data to detect leaks in the tank. The control system receives control commands to control power system 2 and the tank leak detection device.
[0044] Among them, the wide-angle lens is used to acquire visible light images, the infrared lens 6 is used to acquire infrared images, and the laser rangefinder 7 is used to acquire the distance to the storage tank.
[0045] Specifically, the power system 2 and control system need to ensure that the UAV can perform flight path planning and automatic obstacle avoidance. Positioning should achieve centimeter-level accuracy to ensure the accuracy of waypoints. The frame 1 and power system 2 need to ensure that the UAV can withstand winds up to level 7 to ensure the flight stability of the UAV.
[0046] Specifically, the wide-angle lens needs to guarantee a resolution of 4000×3000. The infrared lens 6 needs to guarantee a resolution of 640×512, with a temperature error within ±2%. The laser rangefinder 7 needs to guarantee an accuracy within ±(0.2m+d×0.15%).
[0047] Understandably, the control system can detect tank leaks by sending control commands to the power system 2 and the tank leakage detection device.
[0048] Optionally, the above-mentioned components can be fixed by means of bolts or other parts, and the stability of the connection between the components must be ensured.
[0049] Optionally, the frame 1 can be made of carbon fiber composite or glass fiber composite to reduce the weight of the drone. The power system 2 can be a flat wing, a symmetrical airfoil, or an asymmetrical airfoil. The landing gear 3 can be made of a resilient material, such as aluminum alloy, titanium alloy, or stainless steel.
[0050] Figure 2 A 3D diagram of another drone equipped with a tank leakage detection device, provided as an embodiment of this application. Figure 2 As shown, the drone equipped with the tank leakage detection device also includes: a support plate 4, a base plate 5, and a storage frame 8.
[0051] In some embodiments, such as Figure 2 As shown, a support plate 4 is provided on the inner side of the landing gear 3. The support plate 4 is used to support the base plate 5 above the support plate 4. A storage frame 8 is provided on the base plate 5. The tank leakage detection device is installed in the storage frame 8.
[0052] Specifically, the support plate 4 supports the base plate 5 above it. The base plate 5 supports the tank leakage detection device. The storage frame 8 houses and protects the tank leakage detection device.
[0053] Understandably, fixing the tank leakage detection device in the storage frame 8 can effectively protect the device and also change the center of gravity of the drone carrying the device, thereby stabilizing the drone's flight trajectory.
[0054] Optionally, the support plate 4 and the base plate 5 must be sufficient to support the weight of the tank leakage detection device. The support plate 4, the base plate 5, and the housing frame 8 can be made of aluminum alloy or titanium alloy, etc.
[0055] In some embodiments, such as Figure 2 As shown, the storage frame 8 is designed in a cuboid shape, with openings on its four sides. The openings on opposite sides are identical. The openings on the four sides of the storage frame 8 are either short or long.
[0056] It is understandable that the storage frame 8 has four openings on its side to allow it to open and close, thereby maximizing the performance of the tank leakage detection device during leakage detection and effectively protecting the device when leakage detection is stopped.
[0057] Understandably, the storage frame 8 is designed in a cuboid shape, with four side openings divided into short and long openings, which helps to reasonably set up the tank leakage detection device.
[0058] Figure 3 This is a rear view of a drone equipped with a tank leakage detection device, provided as an embodiment of this application. Figure 3 As shown, the drone equipped with the tank leakage detection device also includes: a short side plate 9.
[0059] Optionally, the short side plate 9 can be made of carbon fiber composite material, glass fiber composite material, aluminum alloy, titanium alloy or stainless steel, etc.
[0060] Figure 4 A side view of a drone equipped with a tank leakage detection device, provided as an embodiment of this application. Figure 4 As shown, the drone equipped with the tank leakage detection device also includes: a first inclined plate 10 and a long side plate 11.
[0061] Optionally, the first inclined plate 10 and the long side plate 11 can be made of carbon fiber composite material, glass fiber composite material, aluminum alloy, titanium alloy or stainless steel, etc.
[0062] Figure 5A rear view of another drone equipped with a tank leakage detection device, provided as an embodiment of this application. Figure 5 As shown, the drone equipped with the tank leakage detection device also includes: a second inclined plate 12, a lifting plate 13, and a lifting mechanism 14.
[0063] Optionally, the second inclined plate 12 and the lifting plate 13 can be made of carbon fiber composite material, glass fiber composite material, aluminum alloy, titanium alloy or stainless steel, etc.
[0064] Optionally, the lifting mechanism 14 can be a piezoelectric driven micro lift, etc.
[0065] In some embodiments, such as Figure 3 , Figure 4 and Figure 5 As shown, a short side panel 9 is provided at the short opening position. The top of the short side panel 9 is movably connected to the storage frame 8 via a hinge. A first inclined plate 10 is provided on the upper side of the short side panel 9. One end of the first inclined plate 10 is movably connected to the bottom of the short side panel 9. A lifting plate 13 is also provided on the upper side of the storage frame 8. The other end of the first inclined plate 10 is movably connected to the lifting plate 13. A long side panel 11 is provided at the long opening position. The top of the long side panel 11 is movably connected to the storage frame 8 via a hinge. A second inclined plate 12 is provided on the upper side of the long side panel 11. One end of the second inclined plate 12 is movably connected to the bottom of the long side panel 11. The other end of the second inclined plate 12 is movably connected to the lifting plate 13.
[0066] Specifically, the short side plate 9 and the long side plate 11 are used to open and close the storage frame 8, and the first inclined plate 10 and the second inclined plate 12 are used to lift and lower the short side plate 9 and the long side plate 11 to control the opening and closing of the storage frame 8. The lifting plate 13 is used to move the first inclined plate 10 and the second inclined plate 12 up and down, and the lifting mechanism 14 is used to move the lifting plate 13 up and down.
[0067] It is understandable that the top of the short side panel 9 and the top of the long side panel 11 are movably connected to the storage frame 8 via hinges in order to enable the opening and closing of the short side panel 9 and the long side panel 11, thereby opening and closing the storage frame 8.
[0068] Optionally, the fixed connection of the above-mentioned components can be fixed by bolts or the like, and the movable connection can be fixed by hinges or the like.
[0069] In some embodiments, such as Figure 5As shown, a lifting mechanism 14 is also provided on the upper side of the base plate 5. The lifting mechanism 14 is controlled and connected through a control system. The lifting mechanism 14 is connected to the lifting plate 13. The lifting mechanism 14 is used to drive the lifting plate 13 to move up and down. The lifting plate 13 is used to drive the first inclined plate 10 and the second inclined plate 12 to move up and down. The first inclined plate 10 and the second inclined plate 12 are respectively used to drive the short side plate 9 and the long side plate 11 to lift and lower, so as to control the opening and closing of the storage frame 8.
[0070] The control system controls the lifting mechanism 14.
[0071] It is understood that in this embodiment of the application, the storage tank leakage detection device is fixed in the storage frame 8, and the lifting mechanism 14 drives the lifting plate 13, the lifting plate 13 drives the first inclined plate 10 and the second inclined plate 12, and the first inclined plate 10 and the second inclined plate 12 drive the short side plate 9 and the long side plate 11, thereby opening and closing the storage frame 8, so that the storage tank leakage detection device can effectively detect leakage when leakage detection is performed; and the storage tank leakage detection device can be effectively protected when leakage detection is stopped.
[0072] In some embodiments, such as Figure 5 As shown, the control system is used to control the lifting mechanism 14 to move the lifting plate 13 upward when it receives the instruction to control the tank leakage detection device to perform leakage detection, so as to move the first inclined plate 10 and the second inclined plate 12 upward, and to lift the short side plate 9 and the long side plate 11.
[0073] Understandably, at this time, the short and long openings in the storage frame 8 are fully open. The short side plate 9 is perpendicular to the side of the short opening (i.e., the short side of the storage frame 8), and the long side plate 11 is perpendicular to the side of the long opening (i.e., the long side of the storage frame 8). With the short and long openings fully open, the lines of sight of the wide-angle lens, infrared lens 6, and laser rangefinder 7 are not obstructed by the storage frame 8, maximizing the effectiveness of the wide-angle lens, infrared lens 6, and laser rangefinder 7.
[0074] In some embodiments, such as Figure 5 As shown, the control system is used to control the lifting mechanism 14 to move the lifting plate 13 downward when it receives the instruction to stop the cold leakage detection device of the control tank, so as to move the first inclined plate 10 and the second inclined plate 12 downward, and to make the short side plate 9 and the long side plate 11 fall down.
[0075] Understandably, when the storage frame 8 is in the closed state, the short side plate 9 and the long side plate 11 block the short and long openings in the storage frame 8, thus closing the storage frame 8. At this time, the wide-angle lens, infrared lens 6 and laser rangefinder 7 in the storage frame 8 are located inside the closed storage frame 8 and will not come into contact with external dust, effectively preventing dust from adhering to the wide-angle lens, infrared lens 6 and laser rangefinder 7.
[0076] In some embodiments, such as Figure 1 As shown, the landing gear 3 is designed with an arc shape. Multiple mounting slots are provided inside the landing gear 3, and reinforcing tubes are inserted into the mounting slots.
[0077] Understandably, the landing gear 3 is designed with an arc shape, and the reinforcing tubes installed inside the landing gear 3 are designed to enhance its impact resistance. This is to provide effective cushioning when the drone carrying the tank leakage detection device lands, preventing damage to the tank leakage detection device.
[0078] Optionally, the reinforcing tube can be a rigid material that effectively absorbs and buffers energy, such as a porous aluminum alloy or titanium alloy.
[0079] In some embodiments, such as Figure 2 As shown, a rib is also provided on the lower side of the support plate 4, and one side of the rib is in contact with the outer wall of the landing gear 3. The base plate 5 is fixedly connected to the support plate 4.
[0080] Understandably, the ribs fixed to the lower side of the support plate 4 can effectively assist the support plate 4 in supporting the base plate 5, so as to support the tank leakage detection device.
[0081] Optionally, the base plate 5 and the support plate 4 can be fixedly connected by bolts or the like.

Therefore, the scope of protection of this application should be determined by the scope of the claims.
